I'm a long time SW user, and one that uses most of the wonderful functionality of the program, from boundary surfacing to sheet metal. In general I'm a big fan of the program, but sometimes.... If anyone wants to waste a good couple of hours, or if any lecturer at a drafting academy wishes to pointlessly occupy their students on a day that they would rather visit the local pub, then simply try to recreate a 'engine turning' finish on a part (otherwise known as Damascening). I had such a requirement today, and it almost drove me up the wall. If you're not sure what I'm referring to, then Google 'Images of engine turning'. I had the requirement today of creating such a cosmetic appearance on a part - easy stuff, right? Create a sketch with multiple concentric contours and then a tiny cut extrude to simulate all the brush marks. No - simply because SW doesn't allow you to effectively vary the instances of a linear pattern when mirrored or repeated in a different axis. I know this sounds like a gripe (and it is), but go on - give it a try. I'm genuinely interested in what responses will result. If anyone wants to just sound off and tell me what I should have theoretically done, please don't bother - the chances are very good indeed that I know more about SW than someone who would post such a reply. But if anyone can be bothered to genuinely attempt to replicate the problem, then I would really appreciate the feedback. I've completed the task, but it really got my back up, in terms of SW ineffectuality. It has to be said that the job was done on my 'craptop', as opposed to my seriously powerful office desktop, which didn't help one bit as every feature took forever to rebuild - but still, there are some serious issues with SW, which is fundamentally a single thread/process program - the amount of data it compiles for a simple part is just ridiculous. K.I.S.S.
